This is a great mini pump. The best that I have ever used.Very well buildI agree with some of the reviewes that there are no clear intructions. If you take a few minutes to figureout how it works (before you go on a trail) it will be the best pump.I would recomend it to everybody.

It does what it says and it says what it does... It "Power PUMPS". I've had no issues pumping 26x2.4 tires schraeder or presta. This pump is well built with strong materials, it has smooth action high pressure or high volume and the best thing is I'm saving $$$ on my CO2 bill. I love it, I think is going to stay in my camel bag for years to come.

Good, dual mode pump for all types of cycling. I find it very odd why so many people say this is hard to pump. Are you a bunch of 4-year olds? You probably just don't know that it has High Volume and High Pressure modes.Also, this pump head design is one of the best thought out ones out there (even better than those supposedly "smart" pump heads). Only an idiot wouldn't know how to operate it.The gauge isn't very accurate, but it's better than nothing.A T-handle would be more ergonomic, but as it is the handle is a good diameter and has a good texture.Great aluminum construction.Mine is the first generation model since it was updated who knows how many years ago (10 years?). It's starting to show it's age though, and I'm afraid I may have to replace it soon.

I had this pump for over 4 years. It's a bit long but it sure inflates tires fast. Once in a while after inflating past 80 psi, the internal check valve seal gets hung up. No worries, I disassemble it on the spot and free up the rubber flapper and continue on. I seen smaller pumps that have stroke life spans. I'm glad I have this pump, it saved me and fellow riders a few times. By the way, once u lubricate the air chamber seals, the pump Inflates tires a lot faster and stays cooler.

I can see why this pump has received mixed reviews. It is very effective when it is functioning the way it is intended to. Although it isn't reliable in that it seems hell-bent at times to not do what it is meant to. If I was racing I would not bring this pump. If I had time and patience, fine, but if I were in a hurry-I would find something more user friendly. My pumps pressure indicator didn't want to work fresh out of the package. Bit of a bummer but life goes on.

This pump is pretty good, but there are better pumps out there for the money. My main complaint is the handle shape--when inflating to high pressure, it's hard to actually finish the pump stroke. It's a decent pump, but I'd buy a more ergonomic one for long term use.

There are no instructions on how to use this unusual pump. It is not intuitive at all. The cryptic pictures on the packaging do not help much in figuring out how to operate the pump. It does not stay attached very well when used on a Presta valve. It is quite hard to pump in one setting, and is quite hard to build pressure in the other setting. Fail.

The pump was $10 (Awesome deal, or so I was told)I was told because they bought so many they got a bargain and passed it onto the consumer... Turns out the pump is simply a poor pump, I cannot see a small woman or child being able to pump a tire up with this pump.I made the mistake of reading reviews after I purchased it..

Can't get enough air into my tires to get the gauge to even start moving. Air leaks out somewhere in the handle, such that if you stop pumping, the tire loses air at a very significant pace. I can't actually get enough air into my tire to safely ride it. This terrible pump has literally rendered my bike unrideable until I can buy a different pump.

This is a terrible product. The first time i used the pump the rubber collar in the pump that is supposed to seal on the valve was too small. The fit was so tight the rubber collar got stuck on the valve and would not come off. I had to use pliers to pull the rubber gasket off the valve and ended up ripping my tube at the valve stem. Luckily i thought to try the pump before i really needed on the trail.

I am sure some people have had a great experience with this pump. My thought is quality control on this product is very poor so it is a 50/50 shot on whether you will get a good pump. Some of the plastic pieces on the pump had already started to fall off when i unboxed it.

Like others have said in reviews the instructions are non existent. I watched an online video to make sure i was using it correctly and the still fell apart.

My advice, pay a little extra for a better pump. If you buy this one you are taking a big chance on throwing your money away.

I only bought this pump cause it was on special and i thought it was a good size to put in my backpack but really it's a piece of junk. Once you get to 20psi it really won't inflate any further, it would take forever to inflate it to a rideable pressure. Spend the extra cash and get something better

First of all, it takes a while to figure out how this thing works. But the main problem is that it leaks no matter how you try to adjust it to the valve. That, added to the impractical handle design makes it is impossible to keep inflating past a certain pressure- it leaks at a higher rate than you can pump air into. Don't waste your money on this piece of junk.
